OAKLAND — Port of Oakland commissioners this week will vote on whether to enter into exclusive negotiations with the Oakland A’s to build a stadium at Howard Terminal, the first step in a yearlong review of the property.

The one-year pact, known as an exclusive negotiating agreement, allows the A’s to study the economic potential and environmental issues at the 50-acre property near Jack London Square.

Last month, team President Dave Kaval and Mayor Libby Schaaf announced the A’s would also enter into a similar agreement with the city of Oakland to assess the Coliseum site. Oakland City Council needs to approve the deal.

“At this point it’s really critical to preserve as many options as possible in Oakland,” Kaval said Tuesday.

The “parallel paths” approach began after the Peralta Community College District board in December ended talks with the A’s to build a stadium on 13 acres at the corner of Fifth Avenue and East Eighth Street.

More constraints exist at Howard Terminal than the Coliseum, where environmental reports are already completed. The site at 1 Market St. is cut off by rail lines, requiring pedestrian bridges or an aerial tram as the team suggested recently. Privately owned Schnitzer Steel is to the west.

If approved at Thursday’s meeting, the exclusive negotiating agreement would be the second time a group studied building a stadium at Howard Terminal. In 2014, an effort led by a team of Oakland businessmen, the Oakland Waterfront Ballpark, was rejected by former A’s co-owner Lew Wolff. Wolff said the waterfront plan was not feasible.

Former Oakland City Administrator Dan Lindheim said at the time Major League Baseball also did not want a ballpark on the estuary.

“The reason was it was on the wrong side of the tracks,” Lindheim, now an assistant professor at the UC Berkeley Goldman School of Policy, said recently. “Major League Baseball feared in the event of a catastrophe. their illustrious fans and players would be stuck. They didn’t want 40,000 people stuck over there.”
